Dell PowerEdge R750 2U rack server

The Dell PowerEdge R750 is a 2U rack server built for enterprise workloads that demand high core counts and large local storage. Dual Intel Xeon Gold 6338 processors provide 32 cores at 2.0 GHz with 3.2 GHz turbo. One hundred and twenty-eight gigabytes of DDR4 memory and twenty-four 600 GB SAS drives fill every 2.5-inch bay.

Virtualisation hosts and database clusters

This configuration suits teams running dense virtualisation, large databases or analytics jobs that benefit from many cores and fast local disks. Buyers who need GPU acceleration, NVMe-only storage or a smaller 1U form factor should look at a different chassis.

PERC H755 RAID controller with 8 GB NV cache

The Dell PERC H755 handles all twenty-four drives and supports RAID 0, 1, 5, 6, 10, 50 and 60. Its 8 GB non-volatile cache protects write performance during power loss. Confirm the RAID level and drive count match your redundancy plan before deployment.

Perguntas sobre este artigo

How do I install the PERC H755 RAID controller and what step is commonly missed?

Seat the H755 in a PCIe Gen4 slot, attach the SAS cables to the 24-bay backplane, and enable the controller in BIOS before creating virtual disks — skipping the BIOS enable step leaves the drives invisible to the OS.

Which components will need replacement first under continuous operation?

The 24 Enterprise 600GB 10K SAS drives and the two 1400W platinum PSUs are the primary field-replaceable units; the H755's 8GB NV cache battery also degrades over time and should be swapped per Dell's schedule.

What thermal or power limit appears first when the dual Xeon Gold 6338 CPUs run at 3.2GHz turbo sustained?

The 1400W redundant PSUs set the power ceiling; prolonged 3.2GHz turbo on both 32-core processors can hit that limit before the 2U chassis airflow becomes the bottleneck.
